I am constantly accused of never innovating, and this vexes me. I have worked hard to try new things in my RPGs and stretch the genre, and I've been doing this from day one.

Example: Avernum doesn't have one storyline. It has three. The game has three long, arcing, game-winning quests, each of them almost entirely separate from each other. It is possible to achieve one of them, say escaping the underworld, be told you have won, pat yourself on the back, and never realize that the game still has two epic storylines remaining.

They aren't three different endings. They are three different games.

I did two games this way, and I've never seen another RPG that does the same thing. I eventually let it go to focus on more detailed single stories, but I still think it was a really cool idea.
